The Pig is back - now with a hook and a spring in his step!
He's about 4 inches tall, though I've printed him at 50% height and he prints fine.
You'll need something kind of sharp (I used a small flat head screwdriver) to spring him open, but in less than 2 minutes after printing, he was ready to go.
The filament for the pictures is Winter Blue Glitter Flake from ProtoPasta.
Credits for the original Springo idea (and his excellent instructions on making your own) go to Devin Montes - check him out at Make Anything.
